Shredder killed off nearly all the yaupon on my 4 acre lot. Just took persistence, IE shredding every 3 months. The roots die eventually if they never get sun. They can't live forever without photosynthesis.
Perhaps mesquite is different..never attacked it with a tractor before, just a saw. It's the damn beans that get you, and if you let shoots come up and resume photosynthesis, they'll keep the roots alive, so I suppose you'd have to shred very often for a long time, and it would be a pain in the arse. I guess as drought adapted as it is, it would just go dormant, and keep coming back.
I'll defer to the experts on this one. Oh well, if you chop it down, it's out of your way for a while at least.
Somehow, I get the feeling that pouring a mix with diesel on stuff isn't quite legal, but it's been done so long nobody cares one way or the other. If it works, it works.
I'll leave the mesquite killing to the experts, and go back to killing Yaupon. I'm good at that.
